Application filed August 22, 1900. Serial No. 27,727. (No model.)

T0 LZZ whom it may con/cern,.-

Be it known that we, IsAIAH D. CHRIT- TON and LEONARD C. KEENER, citizens of the United States, and residents of Cloud county, in the State of Kansas, have invented a new and useful Lister-Disk-Attachment Machine, of which the following is a specification.

Our invention is an improved leveling attachment for lister-plows adapted to coper-l ate with a lister-plow for leveling corn-lands from which crops of listed corn have been removed and preparing said lands for the sowing of wheat, rye, oats, or other small grains.

The object of our invention is to providea cheap and simple mechanism which is adapted to be readily attached to any lister-plow of usual form and to'operate in connection therewith for the purpose of leveling the ridges thrown up by the lister-plow in the cultivation of listed corn and for filling in furrows between said ridges.

2 of the drawings, and isconnected to the.

beam of the lister-plow by braces 2 3. The said beam 1 is thus supported at any required distance in rear of the lister-plow and at aA suitable height. The' braces2 3 are secured, respectively, to the beam of the lister-plow by bolts 4 5, and the rear ends of said bracesare respectively secured on the upper and lower sides of the transverse beam 1 by means of bolts 6.

On the rear side of the beam 1, ne'ar the ends thereof, are brackets 7. The said brackets are provided with longitudinalslots 8. Bolts 9, which secure said brackets to said beam 1, operate in said slots 8, and thereby admit of the adjustment of said brackets 7 longitudinally of said beam l, so that said carrying a scraper 19.

brackets may be moved toward or from each other and secured at any required distance apart and at any required distance from the furrows formed by the listerplow. The said brackets 7 are each provided with a depending arm lO. Blocks 11 are secured on the rear sides of said arms 10,eaeh by a pivotal eyebolt 12. The said blocks and the said brackets are provided on their opposing sides with matched serrations 13, which admit of the adjustment of said blocks on their pivots and assist in maintaining said blocks in position when adjusted.

Vertically-ad j ustable standards 14 are secured lin ,the eyes at the rear ends of the eyebolts 12 and in recesses or grooves 15, which are radial and are made in the rear sides of blocks l1. The said standards a re secured to said blocks at any desired vertical adjustment by said eyebolts, and the blocks 11 being adapted for pivotal adjustment, as hereinbefore described, the said standards may be secured at any desired inclination. Each of the said standards Carries a disk 16 of the usual form, the said disks being journaled on spindles 17, which are bolted to the lower ends of said standards. The said disks are secured on the inner sides of said standards, with their concaved faces disposed opposite each other. Also bolted to each of the said standards 14 is an arm 18, eachl of said arms Said Scrapers operate on the inner sides of the disks 16 and keep the sameclear of earth, as will be understood. The disks 16 being disposed in rear of and Yon opposite sides of the lister-plow, our improved attachment, in connection with the lister-plow, is adapted for use in leveling land from which a listed crop has been removed, the lister-plow being so operated as t'o break ldown the ridges and the disk 16 operating in rear of the plow and in the furrows between Athe ridges and serving to pulverize the soil and to level the same, as will be understood. Having thus described our invention, we

- claim- TOO said noltsand against said blocks, and disks carried by said standards, substantially as del5 scribed.

In testimony whereof we have signed our names to this spccifcation,in the presence of two witnesses, this 16th day of August, A. D. 1900.
